Ring, insulation system can gradual aging, finally lose its due performance, lead to insulation breakdown, it is impossible to continue safe carry out work
Make, therefore the reliability of operation of motor is largely determined by its insulation performance.The insulation system of motor mainly has the turn-to-turn exhausted
Edge, slot insulation, overhang insulation and lead wire insulation, wherein slot insulation are specifically exhausted between coil and stator tooth or stator core
Edge to completely cut off different electric conductors, does not require nothing more than it with good insulation performance, while some also need to have both supporting role.
The shape of stator slot is varied at present, as peariform slot, parallel teeth peariform slot, oblique shoulder flat-bottom slot, circle shoulder flat-bottom slot,
Semi-open slot, open slot etc..For such complicated stator slot, current slot insulation mode mainly has insulated paint and insulating paper
Two kinds of forms.Insulated paint is in insulation, heat-resisting, electrical performance demands are higher, is also subjected to the centrifugation fortune of prolonged motor
Dynamic, in addition to this, insulated paint impregnation technology is complicated, dries that the molten time is long, and slow curing, the volatilization of solvent causes to waste and pollute ring
The shortcomings of border；The paper material that insulate can gradually degrade under the factors such as electric stress, thermal stress, mechanical stress, and then decompose and generate water
Point, the by-products such as alditol, Hydrocarbon Organic, wherein the portion of product using moisture as representative again can be old as catalyst accelerated decomposition
Change, directly affect the service life of motor.
